Swift
Fox on the prairie at Pawnee National Grasslands in ColoradoJune 2009

A story of success:
A small speedy fox, the Swift Fox was once numerous in the Great
Plains. Populations declined so dramatically, as a result of
human activites, that
the Swift Fox was added to the US Endangered Species list.
With protected status, populations recovered sufficiently to be
removed from that list. It is still considered endangered in
Canada, where reintroduction efforts continue.
